What is enhancement type mosfet?

In most circuits, this means pulling an enhancement-mode MOSFET's gate voltage towards its drain voltage turns it ON. In a depletion-mode MOSFET, the device is normally ON at zero gate–source voltage. Such devices are used as load "resistors" in logic circuits (in depletion-load NMOS logic, for example).

Why Mosfets are used?

MOSFET and Its Applications. The MOSFET (Metal Oxide Semiconductor Field Effect Transistor) transistor is a semiconductor device which is widely used for switching and amplifying electronic signals in the electronic devices.The MOSFET is a three terminal device such as source, gate, and drain.

What is the inversion layer in a Mosfet?

The complementary MOSFET is the p-type or p-channel MOSFET. It contains p-type source and drain regions in an n-type substrate. The inversion layer is formed when holes are attracted to the interface by a negative gate voltage. While the holes still flow from source to drain, they result in a negative drain current.
